This invention. relates to an improved construction of ring travelermore particularly adapted for (use in twisting machines and an object ofthis invention isto-so' construct a traveler of this character thatitwill be balanced to hang vertically on the rin r and yarn andtherefore will float more freely and not cramp on the ring when rapidlyrevolved about the package on which the yarn is being wound.

. With these and other objects in view, the

inventionconsists of certain novel features of construction, as will be:more fully de-' scribed, and particularly pointed out in the Inthea'c'company'ing drawings: t Figure 1 is a perspective'view showing myimproved traveler as mounted on a vertical twisting ring.

. Figure 2 is an enlarged'perspe'ctiveview of my improved traveler;

Figure 3 shows thetra-veler; in vsectionas mounted on'a ring in sectionvwiththe yarn extendingthrough the traveler to the package. 1 I i 7Figure 4 is a vlew showing-the ring 1n sec tion and my traveler mountedthereon.

Figure 5 shows the traveler partlally 1n 1 section and mounted on a rina ortion of which is shown. v a V It is found in practice that the oldstyle traveler for handling the heavier'yarns such as cord for cordtires andother heavy twisted yarns and the like is so ou'tof balancewhen running that it has a tendency'to swing or cant at an angle to theaxis of the ring when running and so touch and scrape on the insidesurface' of the ring thereby removing the lubricant therefrom and somaterially increasing the dragging friction of the travelerwhichnoticeably affects the quality of the yarn by stretching and destroyingthe elongation of the yarn and requires that the ring shall be much morefrequently lubricated. To obviate these serious difliculties I haveconstructed a traveler whichhas a relatively straight shank portion toextend substantially in a straight line between the hook shaped endportions which engage the upper and the lower edges of the ring and Ithe ring. is in a vertlcal ipositionfiit doesnot tip or? i-have'fsoconstructed thelshankportion the traveler-that it is of a widthsubstantially less than thatof either of its hook portions,

by which construction it willbe seenthat in order'to obtainthe requiredweight of traveler. I am enabled to extend the width and thereforeincrease the weight ofboth these top and bottom hook members.- Whileproportionately increasethe weightof the lower hook portionwhichincreased weight willserve to cause the traveler to run in a verticalposition while rapidly travelling about j i It will be seen that when"the traveler cant over and therefore the shank does not scrape thesurface of, the ring to removethe portion, the suspension ofthetraveler. on

the yarn causes the traveler. to float aboutthering' with the resultthat-fa much better and more uniform twist and elongationis obtained andthis traveling is controlledby Also the workingv life of thetraveler isincreased and' the lubricant is required to be appliedmuch less" oftenthan'when the .old

style of traveler is employed. The follow '80 c the addedweight ratherthan by friction.

ing is a'detailed description of the present? embodiment of my inventionand showing one construction .of traveler bylwhichthese advantageousresults may be accomplished:

With reference to the drawings, 10 .des1gnates the usual twlsting ringmounted inthe rail 11 so that the axis thru its center willbe vertical.A traveler. used in a twisting machine for instance such as is-employedto handle yarns 1n the form of a cord or other heavy twisted yarn usedin the construction of so- -called:cord tires or shoesfor motorvehicles,

heavy ducks, etc, must be specially constructed for its work and inorder thatlthesejtravel- 'ers shall stand up underthis heavy work-and Yfunction properly it is necessary that the traveler be so built orconstructed as to hang 7 and not swingofiat an angle to this axis and socramp its upper or its lower hook-shaped 7 surfaces upon the edges ofthe ring, thus retiming the dragging friction to the minimum and nicelycontrolling the twisting and winding effects of the yarn or cord as ledupon the package or spool and to accomplish this in a simple andeffective way, I have formed the traveler with a shank portion 12 whichis sub- 'stantially straight, that is, it is not made in loop form andso is much less liable to tip and cramp and this shank portion serves todirectly connect the upper hook shaped end portion I3'and the lowerhook-shaped end portion 14, which hook-shaped ends are adapted to engagethe corresponding upper and lower edges of the ring 10. I preferablyform this travelerfrom a ribbon of stock having a uniform thickness, thestock being preferably rounding or oval in cross section as at 15.0nitsinner surface so that whenthis rounding surface is-in contact withthe ring the contacting area will be reduced and so reduce to theminimum" any scraping or abrading action that this carrier may have uponthe rmg "whencontacting with the same; also thls rounding surfacereduces the abrading action on the yarn as it is drawn thereover. V I donot, however, limit myself tomaking the traveler with a rounded innersurface as this surfacemay be made flat, if desired.

s It isalso found to be of advantage to reduce the shank portion of thetraveler throughout its length-and to reduce this materially so that itswidthwill be substantially less than that of the hook-shaped endportions. The purpose of this reduction: is to reduce the weight and thefrictional action ofthe traveler at its middleport-ion whereby in orderto bring this traveler up to the required weight I am en- -abled toemploy aheavier upper end 13 which is to be carried on the yarn and asubstantially heavier lower end 14 which latter serves as arbalancingweight to maintain the traveler in vertical pos1t1on whlle runnlng. In.some lnstancesI may reduce the width of'this shank to substantiallyone-third that of the hook end portions.

In some instances al'soit is found of'advantage to ofiset the upperendof the shank portion. as at 16 outwardly fromtheplane of the backofvthe shank to provide suflicient room forthe travelling yarn. Y

- In'my improved traveler the yarn 17 rides across the upper portion ofthe narrow shank fitthflp'OlHt 18 and the: shank 12 setssubstantiallyparallel with the inner surface of the ring and the weightof the lower hook end14 is. sufficient to hold the travelerin asubstantially upright position when running thereby preventing crampingand by being of the required weight this traveler floats on the yarnwhich is rapidly running through the same.

My improved traveler is preferably formed of a non-corrosive materialsuch as bronze or the like and therefore does not require hardemng.

This traveler is extremely simple and practical in construction and iseffective in its operation and by its use much less lubricant isnecessary on the rings owing to the reduction of both friction and heatand also by its use both the spindle speed and production maybematerially increased and a better qualthe use of the old style traveler.

The foregoingdesoription is directed solely towards theconstructionillustrated, but I desire it to be understood that I reserve theprivilege of resorting to all the mechanical changes to which the deviceis susceptible,the invention being defined and limited only by the termsof the appended claims.

I claim-- I 1. A traveler for ring twisting adapted to run in a verticalposition about its ring, the

same comprising relatively wide hook-shaped end portions, and arelatively narrow and sub-' stantially straight shank portionconnectingsaid wide end portions, the: inner surface of tion connectingsaid wide end portions, the 1 inner surface of said traveler beingconvex. 3.
